SPECIFICATION forming part of Letters Patent Ido-286,584, dated October 1 6, 1858.

l Application filed January 2?, 1883. (No model.)

[o all when?, t concern:

Beit known that I, lWILLIAM IV. Bovine- TON, residing at Highland Park, in the county of Lake and State of Illinois, and a citizen of the United States, have invented new and useful Improvements in Window Frames, of

' which the following is a full description, reference being had to the accompanying drawings, in which- VFigure l is a vertical section of a windowira-me; Fig. 2, a horizontal cross-section of one side of the frame; Fig. 3, a cross-section on `line x .fc of Fig. l; Fig. e, aseetionon line 1 2/ y oi' Fig. l; Figs. 5 and (i, section and side elevation of the strengthening-plate.

The object of this invention is to improve the construction and operation ofthe wi ndowframe described in Patent No. 245,156; and its nature consists in providing the upper part of the swinging section of the frame with additional securities, and in providing the lower part of the same section with additional seeurities and an improved operation, as hereintached to the jambs D, while the` lower por-` atcr more particularly described and claimed. In the drawings, Aindicates the windowsill; B C, casings; D, jambs; E, rear casing or guide-strip; F, swinging section of sash-frame;

G, upper and fixed portion ofthe sash-frame, a, metallic pla-te for strengthening the section F and furnishing a pivotal bearing therefor, b, khub or boss forming a pivot upon which the frame F turns; c, thumb-screw; d, screw nut or plate; d', cross-plateye, groove in the casing E; j', double orundercut bevel; g, curve ofthe lower end of the frame F; Iz, notch or groove for the casing B; i andj, sash-grooves, and i: stop for sash to rest on when opening.

The window-sill A and the jambs D, with the top plate or sonit, are made in the usual manner, and the casings B, C, and E are also made in the usual manner, except as hereinafter particularly mentioned. The sections of fthe window-frame proper are provided with the usual sash-grooves, i j, and the up per portion of the frame Gr is permanently attion is pivoted to the jamb at b. The jointtf is made with the original bevel to prevent the rising ofthe pivoted part of the sash from 5o locking in turning, and it is also madewith an. under-cut, as shown, so as to' direct and hold the upper end of the pivoted frame against the jamb and give the sash-frame a finished appearance in addition tothe inl proved locking and supporting of its upper end.

In order to prevent the upper end from splitting orwarping, a metallic plate running nearly or quite its width is screwed or otherwise permanently attached thereto, and the thumb-screw c passes through this plate and also into a plate' or nut, d, fastened in the jamb D; By the arrangement of this thumbnut or set-screw c, I avoid the inconvenience and use ofa screw-driver or wrench, together with the liability of marring the frame by the Vuse of such tools, and in combination with the under-entf, I am able to give the upper end of the pivcted frame F a firm support and a firm locking in position by means of a single set-screw. It will be understood that a similar set-screw maybe used on the opposite side; but if not used' it will be desirable to apply the plate to prevent swinging and warping. Ordinarily a screw7 c, will be used on both sides. The screw c may be made ornamental and in the form of a small knob, if desired, and it may also be furnished with a cap to prevent the marring ofthe wood when screwed down, as shown in Fig. Li.

At the lower end of the frame F the crossplate a is placed, and fastened with screws or turning of the frame or lock it to the jamb, Y

and by this arrangement the frame is not liable to be split if, by any mischance, it should be dropped or partly dropped while its upper end`was being lowered, and by curving the lower end, as at g, and cutting out the casing B, as at Iz., a complete finish can be given to Vthe frame and casing without cutting so as lto IOO 'The double-bevel cut f is to be made high enough in the sash-frame, so that when it is desired to turn the pivoted portion down, the upper sash can be run down in the groove and be turned down with the lower one .for the purpose of cleaning, repairs, or such other purpose as may be desired, and by this arrangement, when the weights are made detachable, either sash can be readily removed from the sash-frame when it is turned out of position, andbe replaced and returned to p osition without diiiieulty or delay, and by this arrangement of the supporting-plates, locks, pivots, and undercut top the sections F do not need to be connected together by cross-bar or otherwise. Y

I am aware that a sash-frame has been composed of two sections beveled at their adjoining edges, and the lower section pivoted at its lower end to the jamb, to swing back for the purpose of cleaning the outsides of the sashes and panes; and I am also aware that a window-sash has been pivoted to strips arranged to slide vertically on the jambs, the pivots comprising central]y-perforated plates fixed in the sash and the sliding strips, respectively, and a screw-bolt passed through the plates from the sides oi the sliding strips which are next to the jambs, the end of -the bolt being screwed into the plates which yare set in the 4o sash. Such features, therefore, I do not claim.

What I claim as new, and desire to secure by Letters Patent, is as follows:

1. The combination, with a window-frame provided with the fixed section G, having its 45 lower end inclined downward and undercut,v as described, of the pivoted swinging section F, having its upper end double-beveled to fit the inclined and undercut lower end of the iiXed sections, substantially as described.

2. rlhe combination, with a window-frame having the fixed sections G, swinging sections F, and the plates c, having the hubs b, and secured to the back sides of the swinging sections, of the screws b, passing through the 55 hubs of the plates from the outsides of the swinging sections, and the swinging sections with the hubs having loose bearings on thel screws, to turn thereon independent of any movement of such screws, substantially as de- 6o scribed.

3. The combination of the pivoted sections F, having the curved corner g, with the casing B, having the notch h, substantially as speciiied.

4. The combination and arrangement of the pivoted frame F, having its upper end beveled and its lower end rounded, as described, with the section G, jamb D, casing or strip E, having the groove e, and the casing B, having the notch or notches h, all constructed and operated substantially as described.
